Knowing that there is no ECU upgrade for the 2k-2k1 max, I would like to know which program would best suit a fully bolt-on 2k max?

SAFC, VAFC, Emanage, etc.

I know this isn't comparing apples and apples. I would probably end up altering the A/F ratio, but who knows yet. Also, I understand that Emanage will "hopefully" be able to extend our rev limiters, do you guys see this happening, because this would be important in my decision. If not, would I just be better off going with the VAFC? Thanks!

 

If you might not end up altering the A/F why even purchase these products?
Also I havent heard of a max sucessfully raising the rev limiter with the E-manage ultimate

 

i would advise a dyno before even considering a purchase. my max had perfect a/f with my cattman y pipe but headers made sure that didnt last. every car is different but 3 pulls w/ a/f would help lead you.

It has not been perfected though.

Emanage Ultimate is obviously the most capable in tuning, but it is also the most expensive and complex. There are several threads in the SC/TC and NA forums about both.

If you want something simpler and cheaper get a VAFC over an SAFC since it can control your VIAS or any other RPM based function and it has more cells for tuning. It is also not much more IIRC.

 

don't blow the money on a piggyback before seeing if you even need to adjust the AF mix.

 

i was lookng at the emange, for both the af adjustmaent as well as the rev limiter adjustment, my tunign shop was confident that my car wouldnt be much of a problem to do what i want. are other people having problems with it?

 

Thanks guys for the responses. I will run a few dyno's before doing any AF altering.

What's the deal with Emanage and our raised rev limiters... are they just being slow and lazy?

 

The real power comes in advancing the timing, not so much the A/F ratio.

 

if they ever get that adapter or figure out the emanage ultimate on how to advance timing....it would be great!

actually, does anyone know if you swap in the vq35 shortblock and put our heads on it, would you be able to use the vq35 crank position sensor? therefore the emanage ultimate would work fine...since 350z's are advancing timing and extending rev limiters just fine I believe...

 

nope, won't work. The vq35 CPS needs the vq35 flywheel.

 

right...so the only way to use the vq35 shortblock and vq30 heads with the vq35 cps is to use the vq35 flywheel...but then that would necessitate the need for the 6spd right?

 

yep, you'd have to use the 6spd, 5.5gen ECU, and E-GAS as well. You don't want to use a vq30 heads on a vq35 because the vq35 heads flow better.

 

yeah I know that they flow way better, but I kinda like the higher compression you would get with the VQ30 heads...plus if I had them port and polished...and the fact that knowing I am not utilizing the VTC's with using the VQ35 heads, would bug me terribly unless I did swap over the entire harness which would be a huge hastle and cost...the idea that there is untapped power would bother me till I got it to work...

 

The vq35 heads have biggers valves. With a vq30 heads that are ported and polished and using the 00vi, you might be able to get close or match the peak power of the vq35 heads with the vq35 IM. But the vq35 heads have a lot more low and mid range torque. This is dyno proven. Who cares if you can get a higher CR with the vq30 heads if the vq35 heads make more power and TQ?

In addition, the vq35 heads have bigger valves so you'll always have more potential with the vq35 heads. The vq35 heads have better cooling so you can advance the timing much more than you could with the vq30 heads.

IMAO, if you want the crown for the most powerful all motor maxima, you would:

-use Mallfinder heads
-use the 00VI
-use the 5.5gen TS ECU
-tweak the A/F ratio and advance the living $hit out of the timing
-put in the ARP rod bolts
-use cattman headers and catback exhaust. Maybe upgrade to 2.75" exhaust.

The 6th gen 6spd would help it to be faster since it has a more aggressive final drive gear.

 

but if you use the 5.5gen TS ecu....you would have to swap the entire wiring harness over....I would consider a vq35 out of the pathfinder so I could use the 00VI...

maybe smt6 or smt7 I could advance the crap out of the timing or when they or if they ever get the emanage working...that way I could skip the TS ecu and save more money...cams, valve springs and a increased rev limit (once again if they get the emanage working)...would breath pretty good up top I would think....I didn't know that people are still getting with I/H/E/AFR tuned are still getting 230WHP/230WTQ with our 4 or 5th gen ecus....no VTC's...which is impressive...so I would think advance the timing a ton and maybe the rest of the mods...ie. flywheel, udp, and cams would net me the rest....

 

Yep.

Can't do that, it's RWD. You'd need a FWD block or you won't be able to mount the engine.
